When your origin stops responding, you shouldn’t have to dig through layers of logs or guess whether it’s DNS, timeouts, or misconfiguration. Origin Errors Monitoring gives you full visibility into failed origin requests, directly in the dashboard or via API. Available for all users at no extra cost.
